Mastodon and Misskey(or other Misskey fork) supported ActivityPub Relay. Also support Pleroma and Akkoma.
I refereced these software codes when implementing ActivityPub Relay. Thank you for these software implemented and maintained.

You do not need Redis, Nginx, nor PostgreSQL to deploy this Relay.
